Solving linear boundary value problems for linear systems of ordinary differential equations
(2019-12-09)
This research studies the behavior of a numerical technique, known as Continuous Orthonormalization (CO), when computing the eigenfunction for the Orr-Sommerfeld equation (OSE). The hydrodynamic stability region of moving ...
Un modelo matemático para evaluar el efecto de herbivoría de la polilla (Oidaematophorus espeletiae Hernández, Fuentes Fajardo & Mathews) sobre el frailejón (Espeletia grandiflora Humb. & Bonpl.)
(2019-05-15)
The Espeletia grandiflora Humb. & Bonpl. commonly known as frailejón is a plant of the Eastern Andes of Colombia, such that its function within the ecosystem is to regulate the production of water. In 2012, it was found ...
The elliptic anisotropic problem with Wentzell boundary conditions and variable exponents
(2019-12-10)
Let $\Omega\subseteq\mathbb{R\!}^N$ be a bounded Lipschitz domain, for $N\geq3$. We investigate the solvability and regularity of a class of quasi-linear elliptic equations involving the anisotropic $\overset{\rightarrow ...
Binning in the chi-square goodness-of-fit test
(2019-07-10)
One of the most commonly used goodness-of-fit tests is based on Pearson's chi-square statistic. Since this requires class intervals for the data, questions arise with respect to the method of estimation, types, and the ...
Modelo para el análisis de los factores asociados con el tipo de parto aplicando bosques aleatorios y regresión logística
(2019-12-11)
Actualmente existe una variedad de algoritmos que tratan de optimizar el proceso de clasificación, entre ellos el algoritmo de Bosques Aleatorios. Uno de los objetivos de esta investigación es desarrollar un modelo de ...
Imagen de los τ-Productos
(2019-05-15)
The theory of $\tau$-factorizations, also known as theory of generalized factorizations, was developed by Anderson and Frazier in 2006. It was the result of a generalization of the comaximal factorizations by McAdams and ...
Paralelización de la operación correlación cruzada aplicado a marcas de agua en imágenes digitales
(2019-12-09)
El uso de marcas de agua permite proteger elementos multimedia frente a manipulaciones ilegales que infrinjan derechos de autor. Marcas de agua construidas a partir de matrices con buenos valores de correlación y autocorrelación ...
The use of the Old Faithful Geyser data in both undergraduate and graduate statistics courses
(2019-05-08)
Many statistics teachers in line with the recommendations of several studies suggest using real-life context data during class lessons. The present work shows the use of the Old Faithful Geyser eruptions as a real-life ...
Estudio comparativo entre INLA y MCMC en modelos lineales generalizados mixtos
(2019-12-09)
In this work a comparative study is carried out between Integrated Nested
Laplace Approximation (INLA) and Markov Chain Monte Carlo (MCMC) for estimation in Generalized Linear Mixed Models (GLMMs) for count data and binary ...
Análisis y cuantificación de los indicadores de incivilidad percibidos por los estudiantes del RUM en sus áreas de vivienda
(2019-05-13)
The insecurity perception affects people’s quality of life. That is why, the aim of the thesis is to analyze and quantify the indicators of incivility perception, which is one of the factors that affect this problem. The ...
